Introduction
An acoustic neuroma is a benign non-cancerous growth, or tumour, in the brain. It's also known as a vestibular schwannoma.
Symptoms of an acoustic neuroma
A small acoustic neuroma may not cause any symptoms, or your symptoms may develop gradually as acoustic neuromas tend to grow slowly.
Causes of an acoustic neuroma
In most cases, the cause of an acoustic neuroma is unknown. The only known risk factor is having a very rare genetic condition called neurofibromatosis type 2.
Diagnosing an acoustic neuroma
An acoustic neuroma can be difficult to diagnose because the symptoms often develop gradually and can be difficult to spot.
Treating an acoustic neuroma
Small or slow growing acoustic neuromas are often closely monitored. Surgery or radiotherapy may be needed for larger or more agressive tumours.
Complications of an acoustic neuroma
The symptoms of an acoustic neuroma can affect your day-to-life, but more serious complications are rare.
